Japanese pattern of supply chain (2)

i have a practicle example, though i will not disclose the names, A MNC runs in XYZ country can get the better quality in a better price item than from the home country, but the home company bounds this MNC running in the forign country management to buy that item from the home country just because that supports the home country's economy to a great extent and if the order shifts from the home country to the forign country that will incur loss like unemployment , wastage of resources etc.

i think the home country bounds the other country that must buy atleast certain percentage of the material from the home country to support their economy. That is why the US and Europe export more material to CHina delphi than teh other way around.
